  • Method for correcting the drift of an infrared radiation detector comprising an array of resistive imaging bolometers and device implementing such a method
    Patent number: 9442020
    Abstract: A method for detecting infrared radiation includes the steps of: providing a resistive bolometer retina including a plurality of resistive bolometers suspended above a substrate of a bolometric detector; acquiring the infrared radiation by the resistive bolometer retina to produce a plurality of raw read signals provided by the bolometers; correcting a response dispersion of the resistive bolometers in the raw read signals using a gain table, each gain of the gain table being associated with a bolometer of the resistive bolometer retina.

  • Method for correcting images output by a detector without temperature regulation and detector implementing such a method
    Patent number: 8902316
    Abstract: Image correction methods and systems are disclosed that correct raw values, including, subsequent to closing the shutter, acquiring a current raw value table, determining an offset correction table for the current temperature of the detector as a function of the current table and a set of stored raw value tables, and correcting the stream of raw values using the offset correction table. A maintenance process includes testing a condition for replacing a table of the current set with the current table, and if the condition is met, replacing the table of the current set with the current table. This test includes determining whether there is a new set of tables obtained by replacing a table from the current set with the current table that is more relevant than the current set with regard to subsequently determining an offset table.

  • Device for detecting infrared radiation comprising a resistive imaging bolometer, a system comprising an array of such bolometers and a method for reading an imaging bolometer integrated into such a system
    Patent number: 8080779
    Abstract: A device for detecting infrared radiation including a resistive imaging bolometer, a mechanism for measuring drift in the electrical resistance of the bolometer relative to a reference value of the electrical resistance of the bolometer which corresponds to predetermined operating conditions of the bolometer, and a mechanism for correcting the effects of the drift in resistance or for correcting the drift itself.
